Advanced Science, EarlyView.An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.

Recent Genetic Changes Affecting Enterohemorrhagic Escherichia coli Causing Recurrent Outbreaks
Microbiology Spectrum, 2022 Enterohemorrhagic E. coli (EHEC) is responsible for significant human illness, death, and economic loss. The main reservoir for EHEC is cattle, but plant-based foods are common vectors for human infection.

Adhesins and invasins of pathogenic Escherichia coli
International Journal of Medical Microbiology, 2005 Pathogenic E. coli cause both intestinal and extra-intestinal infections in humans and animals. Bacteria must be able to adhere to host cells if they are to colonize and to invade their hosts. Numerous E. coli adhesins with different morphological features and receptor specificities have been identified.

Advanced NanoBiomed Research, EarlyView.Intermittent catheter use can damage the urinary tract and predispose to infection. We deployed a complex human urothelial model to investigate. Catheter contact induced compressive and shear stress causing umbrella cell disruption, reduced barrier function, inflammation and increased cell adhesion to the catheter surface.

Modulation of Animal Gut Health by Milk Oligosaccharide
Animal Research and One Health, EarlyView.This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

Biotechnology and Bioengineering, EarlyView.Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.
